I have been wondering is there is an adapter for this scenario. I want to connect my sirius satelliate radio and my computer, to the pc speakers i have, its a surround sound (logictect x620). currently the setup I have only lets me connect half of the speakers to the radio, and the other to the computer. It came w/an adapter to connect it to any thing ie. dvd, tv, game consule. I want my computer to use all speakers when i use it, or have the radio use all the speakers, all without having to unplug and replug. Is there a splitter? adapter that will allow me to connect both things to use up all the speakers?? I have been looking w/no avail. Considering upgrading my soundcard if it will let me do such thing.
